Urethane injection material - List of Manufacturers, Suppliers, Companies and Products

Urethane injection

Shorten working hours! It cures underwater and has excellent water resistance.

"Urethane injection" is a speedy backfill injection method using rigid foam urethane. It cures quickly, allowing for immediate use after the backfill work in the cavity. It reaches final strength in just about 30 minutes, starting to harden after 1 minute, using a rapid foaming and curing material. After curing, there is almost no expansion or contraction, allowing for complete filling. It also foams and cures underwater, demonstrating excellent water-stopping properties. 【Features】 ■ Quick curing ■ Immediately available for tunnel use ■ Stable quality ■ Can be constructed in a compact working environment ■ Low cost *For more details, please refer to the PDF materials or feel free to contact us.

Urethane-based injection materials "NEW-TSRF, NEW-TBU"

It demonstrates high cost performance as an injection material for various auxiliary construction methods!

In recent years, tunnel construction sites have been required to respond to strict conditions, such as construction in urban areas and low cover depths. Under such conditions, the "injection-type pre-support method" has been widely adopted as a safe, reliable, and cost-effective auxiliary construction method. Among the injection materials used in the injection-type pre-support method, silica resin-based injection materials are utilized as they meet many of the demands required on-site, including strength, permeability, safety, and even economic efficiency. 【Features】 ○ Compatible with various geological conditions and construction methods ○ Can efficiently improve the ground For more details, please contact us or download the catalog.

High-performance polyurethane for cavity filling and backfilling injection 'AGSR-FI'

It reaches final strength in a short time! It is a highly safe material that takes into consideration the environment and ecosystems.

"AGSR-FI" is a polyurethane foam that cures and expands quickly by mixing polyols and modified isocyanates. It reaches its final strength in a short time, allowing immediate use of the tunnel after construction, and it can cure and expand even underwater, making it usable in spring water environments. By utilizing it as a filling material for back cavities of existing tunnels, it helps restore the structural functions inherent to the tunnel and contributes to the extension of the lifespan of existing tunnels. 【Features】 - It reaches its final strength quickly, allowing immediate use of the tunnel after construction. - It can cure and expand underwater, making it usable in spring water environments. - The foam has independent bubbles, so high water-stopping properties are expected after curing. - Its low foam density means that the load on the lining concrete is minimized. - It complies with the "Guidelines for Safety Management of Polyurethane Injection Materials in Mountain Tunnel Construction." *For more details, please refer to the PDF document or feel free to contact us.

Urethane injection material "AGSR-PSG"

For tunnel auxiliary construction methods! A polyurethane injection material with excellent ground improvement effects and water inflow resistance.

"AGSR-PSG" is a polyurethane injection material (AGSR-PSG) that solidifies by mixing polyol and polyisocyanate, making it a ground consolidation material with high foaming pressure and excellent solidification properties. It is difficult to dilute in spring water environments, allowing for reliable ground improvement through foaming. Due to its low viscosity compared to typical polyurethane injection materials, it has excellent permeability and can facilitate localized improvement around bolts and steel pipes. [Features] ■ Excellent ground improvement effect ■ Low viscosity compared to typical polyurethane injection materials, allowing for excellent permeability and localized improvement around bolts and steel pipes ■ Higher foaming pressure than silica resin, enabling penetration and improvement of fine cracks in fractured ground *For more details, please refer to the PDF document or feel free to contact us.
